Elevator system and method for operating an elevator system

Abstract

An elevator system may include a ropeless direct drive, a rail system, an elevator car, and a brake. The elevator system may also include a component on which there is arranged a sensor for sensing oscillations. The elevator system further comprises a processing unit for calculating counter-oscillations on the basis of the sensed oscillations. The elevator system also include means for generating the calculated counter-oscillations, which may also be disposed on the component. A corresponding method may involve sensing oscillations outside an elevator car, calculating counter-oscillations based on sensed oscillations, and generating the calculated counter-oscillations outside the elevator car.
